int HYPERVISOR_platform_op(struct xen_platform_op *platform_op) to allow compiler type checking and match the x86 version. Also, the implementation of the helper differ from x86. On x86, the helper takes care of setting the interface_version while here you request the caller to do it. It's better if we have similar requirement across the architecture as this helpers may be called from common code. > int HYPERVISOR_multicall(struct multicall_entry *calls, uint32_t nr); > > static inline int Regards, -- Julien Grall -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
